From a Port news release:

Up to six 366-foot-tall cranes will soon be raised 27-feet higher at the Port of Oakland. The Port said that the $14 million-to-$21 million project will begin this spring at its largest marine terminal, the Oakland International Container Terminal. The objective: make it easier to load and unload megaships with containers stacked high above deck.

The Port of Oakland said it will pay to raise the cranes. It added that the terminal operator, SSA, will repay the Port over the life of its Oakland lease.

The terminal said it hopes to begin work on the cranes in April. Completion is scheduled for the second quarter of 2018, depending on how many cranes are raised. That number will also determine the total cost of the project.
